• Low Impedance & Loss — Measured impedance of 57 mΩ and tangent of loss angle (tan δ) of 0.11 at 20°C, 120 Hz, supporting stable performance at higher frequencies.
• High Ripple Current Capability — Low-frequency ripple current 2.895 A at 120 Hz and high-frequency ripple current 3.86 A at 10 kHz; frequency coefficients for 2200 µF are 0.75 (120 Hz), 0.90 (1 kHz) and 0.95 (10 kHz).
• Leakage Current — Specified leakage current of 1386 µA (as provided for this part).
• Reliability & Endurance — Rated endurance of 12,000 hours at 105°C under rated DC bias plus rated ripple current for the UHW series at this voltage class.
• Wide Operating Temperature — Specified operating range from −40°C to +105°C to support a variety of thermal environments.
• Compact Radial Package — Case dimensions φ18 × 40 mm, lead spacing 7.5 mm (±0.5 mm), radial-lead can package available in bulk or bag packing for through-hole assembly.
• Environmental Compliance — RoHS-compliant construction.

Typical Applications

• General Purpose Electronics — Board-level energy storage and smoothing where a compact 2200 µF, 63 V capacitor is needed for reliable operation.
• Power Supplies and Voltage Rails — Filtering and ripple handling on DC rails benefiting from the part’s high ripple current ratings and low impedance at higher frequencies.
• Industrial Equipment — Circuits operating across −40°C to +105°C that require extended endurance (12,000 hours at 105°C) and robust ripple performance.

Unique Advantages

• High Ripple Current Handling: Allows the capacitor to manage significant AC ripple at both low and high frequencies, reducing thermal stress in ripple-heavy circuits.
• Low High‑Frequency Impedance: The low measured impedance and favorable frequency coefficients help maintain performance in fast-switching and high-frequency environments.
• Long Endurance at Elevated Temperature: 12,000 hours endurance at 105°C (for the 63 V class) provides predictable long-term behavior in hot operating conditions.
• Compact Through‑Hole Form Factor: φ18 × 40 mm radial can and 7.5 mm lead spacing deliver a space-efficient solution for legacy or mixed-technology assemblies requiring through-hole components.
• Proven Series Characteristics: Part of the UHW series, which emphasizes miniature size, high ripple current and high reliability for general-purpose designs.
• RoHS Compliance: Environmentally compliant construction for regulated markets and assemblies.
